Read the entire manual before installing and activating the system.
1. DESCRIPTION
The power supply unit is suitable for supplying LEDs and is intended for DIN rail mounting. The output voltage
of 24V DC is stable within a narrow tolerance range, produces very little ripple and is highly efficient. The output
voltage range is adjustable (see technical data).
The total connected load may not exceed 25W (340-00021), 50W (340-00022) or 100W (340-00023). A green
LED on the unit indicates that the power supply has been correctly connected and that 24V DC is available.
The unit has a switch-on current limiter. It is protected against overload, overvoltage, overheating and short
circuit.
De unit complies with safety standards (EN60950-1) and EMC standards (EN55011; EN55022 Class B; EN55024;
EN61000-3-2, EN61000-3-3).
2. FITTING AND CONNECTIONS
The DIN rail power supply unit has two outputs to which LEDs can be connected.
The unit has a width of 4.5E (25W and 50W version) or 6E (100W version) and can be installed in a DIN rail box.
The load must be connected between the '+' and '-' terminals (see fig. 1).

Fig. 1b circuit diagram 100W (340-00023) DIN rail LED power supply.
When all the connections have been correctly made and the power supply is switched on, the green LED lights
up.
Installation advice:
- If you install several modules next to one another, provide a gap between them of at least 1 module using
modified blanking plates.
- The unit should ideally be installed at the bottom of the distribution box.
- Check the temperature. If the temperature in the distribution box becomes too high (max. 35°C), provide
additional ventilation to guarantee an optimum life span. Ensure the heat can be dissipated effectively from
the top of the board. If necessary, fit a fan.
- In case of higher temperatures, use the following output graphs (fig. 2a, 2b and 2c).
